TAPE CASE AND WINDING-DRUM.

Specification of Letters Patent.

Application tiled July 26, 1913.

To all w71 om it may concern lie it known that we, Geenen F. PUTNAM and HENRY H. VVnssENDoiur, respectively citizens of the United States and Germany, residing at the city of Flint, county of Genesee, State of Michigan, have invented a certain new and useful Improvement in Tape Cases and lVinding-Drums, and declare the following' to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to tape cases and drums and has for its object a drum whose rotative bearing upon the ease is wholly on one side of the case.

In the drawings: Figure 1, is a cross section of the parts in position for assembly. Fig. 2, is a cross section of the tape ease and drum assembled. Fig. 3, is an interior plan view of the drum and the half of the case that holds the drum.

The tapecase is composed of two halves a, Z). Onv one half the metal of the face is turned in as at 0 to receive the drum (Z. Each half of the case is notched to form an opening e through which the tapeemerges.

The drum (l may be of any desn'ed construction. lVe have shown a drum which has a pivoted crank j' with a handle g. This handle may he passed through the hole 7i, 1n the end of the drum and held in the interior of the drum by the spring i. A knockout handle, that is, a handle and a crank which are forced outward by pressing o1' releasing a member might be used in connection with the drum. The drum has two slots j in its side walls for the reception of the cross strip le which attached to the ring Z. The ring and the cross strip form a bearing that is journaled wholly in one side of the case by turning the lip e (Fig. l) back upon the ring Z Fig. 2). At the center, the cross strip /c has an aperture m that is screw-threaded. After the bearing unit has been placed, 1t .remains permanently 'in situ. A small screw it passes through the center of the end of the drum and engages with the screw-threads of the aperture m to fasten the drinn to the bearing' unit. It will be noted that this screw is under the crank f when the crank is held against the end of the drum, as shown in Fig. 2. Hence the screw is not exposed when in the pocket or being carried about so that it can be turned out of place and lost. This is one of the main objections to the old form of construction in which the screw was located on the opposite side of the case.

Our invention does away with the central post and allows a perfect plain face on one side of the case.

What we claim is:

l. The combination with a tape case provided on one side with a central opening and a turned-in lip, of a bearing unit journaled wholly in one side of the ease by doubling the turned-in lip upon the bearing unit and a drum fastened to the bearing' unit, substair tially as described.

2. The combination with a tape case having' a side wall provided with a central Opening, of a bearing unit journaled wholly in one side of the case, a tape drum exposed only at the side of the case that journals the bearing unit, a screw for removably fastening' the tape drum at its exposed end to the bearing unit so that when the drum is detached from the bearing unit the drum may be removed through the central opening, and a crank for turning the drum pivoted to the drum and arranged to overlie the screw when the crank is held against the drum in closed relation, substantially described.

The combination with a tape ease provided with a turned-in lip, of a bearing unit journaled wholly in one side of the case, comprising a ring rotatably held by said lip and a cross strip with a threaded central aperture, a drum notched on the sides to straddle the cross strip and a screw passed through the end of the drum and adapted to run into the threads of the aperture of the cross strip, substantially as described.

4l. The combination, with a tape case having only two sido walls and a peripheral inelosure, one of the side walls heilig provided with a central opening, of a tape drum passing through said central opening' and terminating short of passing' into the opposite side wall, and means for journaling and supporting said tape drum wholly upon the side wall through which it passes.

5. The combination of a tape case comprising only two side walls and a peripheral inclosure, one of the side walls being provided with a Cental opening, of a tapel dum ated to'diseonnect thel drum and the bearing passing through said central opening and unit Without disassembhngthe rtape ease.
